A noisy humidifier may be the result of an unlubricated fan motor or a drive mechanism clogged with debris. Periodically clean the water reservoir, fan, and nozzle to ensure they are working properly.
To keep your humidifier functioning smoothly and efficiently, lubricate the fan motor bearings with SAE #20 oil. Be sure to consult your owner’s manual for proper care and maintenance procedures.
Vibrating parts can often cause noise. To check for this:
1) Disconnect the power, remove the cover, and look for any vibrating parts. Tighten loose screws, if necessary.
2) Wiggle the fan to see if it is loose on its shaft. If it is, tighten the mounting fasteners.
3) If the humidifier still makes noise, call an appliance repairperson or take the unit into an appliance repair shop.
